INKI NG APPARATUS FOIR PRlNTING-PRESSES;

SPECIFICATION forming part of Letters Patent No.. 751,351, dated. February 2, 1904.

Application filed February 11, 1.901.. Serial No. 46,925. (No model-l To all whom it may concern.- I

Be it known that I, WALTER SooTT, a citizen I of the United States, and a resident of Plainder.

field, in the. county of Union and State of New Jersey, have invented certain new and useful Improvements in Inking Apparatus for Printing-Presses, of which the following is a specification.

My invention relates generally to inking apparatus for printing-presses, and more particularly to improvements whereby the regulation of the supply of ink can be easily, accurately, and perfectly accomplished, and to other improvements more particularly here'- inafter described.

I have embodied my invention in the rotary printing-press shownin the drawings, in which the inking apparatus is mounted on an independent framework, adapted to be moved back and forth by suitable means on the main framework, to bring the form-rolls in and out of contact with the form on the plate-cylin- The invention, however, consists in making the inking apparatus self containedthat is, constructed in such a manner that when the inking apparatus is moved away from the plate cylinder, from which it derives its motion while operating, it may be operated to ink up all the ink distributing rolls and cylinders by turning a single handle or hand-wheel. This may also be accomplished by the means hereinafter described, whereby the inking-apparatus gearing is kept in mesh with the gear on. the plate-cylinder, but in such a manner'that the form-rolls do not contact the form, so that no ink is transferred to.

the latter.

A further improvement consists in the means whereby the amount of ink supplied by the fountain can be regulated. This is accomplished by means of an adjustable split cam on the shaft of the fountain-roll or on a shaft arrow 8.

In the drawings I have shown a construction embodying my invention; but variations may of course be made to suit various requirements.

Figure 1 is a side elevation of the inking apparatus and adjacent elements embodying my invention. Fig. 2 is a top view of the gear which operates the inking apparatus. Fig. 3 is a side view of the means for running the inking apparatus back from the plate-cylinder. Fig. 4 is a top view at an angle of part of Fig. 1 looking in the direction of the Figs. 5 and 6 are end and side views, respectively, of the means for regulating the supply of ink. Figs. 7 8, 9, 10, 11, 12, 13, 14:, and 15 are modifications of same.

Similar letters of reference indicate corresponding parts in the difierent views.

I shall describe the inking apparatusembodying my invention and adjacent elements of an inking apparatus and afterward point out the novel features in the claims.

A and B represent, respectively, the irn-. pression and plate cylinders mounted in the framework 0 of a suitable construction and provided with a bed-likev extension 0. Upon this extension are slidably mounted the frames D, one on each side of the machine, constructed to carry the inking apparatus and provided with the racks 61, adapted to engage with the gear 03 This gear in turn meshes with the gear d which is mounted on the cross-shaft d and provided with the handle (Z By turning this cross-shaft d the frames D, supporting the inking apparatus,'are carried bodily backward and away from the form-cylinder B, thereby giving access to the latter and also to the form-inking rolls f which can be ren ewed or replaced without destroying their set.

In the frames D is mounted the gear G, which serves to operate the whole inking apparatus either by deriving its motion from the gear I) on the form-cylinder or by means of the handle g. Meshing with the gear G are the gears f, f and f respectively, on the distributing-cylinders F, F, and F Placed around these distributing-cylinders are the rollers f covered with composition, which distribute the ink and transfer it from the cylinder F to the cylinders F and F. From these two latter the ink is transferred by means of the form-inking rolls f, mounted also in the frames D, to the form on the cylinder B. By this means the inking apparatus can be operated when moved away from the plate-cylinder by simply turning the handle g. This handle might of course be attached to any of the other gears in the train of gears shown.

The fountain-roll E is mounted on the shaft which carries the large gear 6 which meshes with the pinion f on the shaft of the cylinder F.

On the same side of the machine as that which carries the gear and pinion just described are the rock-arms J J, J J, and J J J being carried by the stud j and J J and J by the rockshaft,7' On the ends of all the rock-arms are friction-rollers of the usual construction, which engage with collars on the ends of distributing-cylinders F,

F, and F the roller on the arm J engaging with the cam e on the shaft of the fountainroll, by means of which the distributing-cylinders are caused to vibrate in an endwise direction.

On the fountain-roll shaft 6 and adjacent to the cam e is the cam 0, provided with an adjustable portion 6 Between the fountainroll E and the distributing-0y]inder F is placed a rock-shaft K, on each end of which is placed an arm k, the upper ends of which carry the ductorroll L. On one end of the shaft K is also placed an adjustable arm 75 on the end of which is placed afriction-roll 75 which engages with the double cams e and 0". With each revolution of the cams 0* and c the duetor-roll L is caused to vibrate twice between the fountain-roll E and the distributing-cylinder F. In Fig. 15 are shown two cams similar to e and c lettered e and 6 constructed in such amanner that the ductor-roll vibrates only once to each revolution of said cams. The inner edge or circle of the adjustable earn 6 is formed into gear-teeth e, which slide around and turn on the projection e on the earn 6. These teeth engage with the pinion m, whose shaft m extends through the hubs of the cam e and the gear 0 On the outer end of this shaft m is placed the worm-gear m which gear is controlled by the worm m on the shaft m On the end of this shaft m is a bevel-gear N, which meshes with another bevel-gear a on the shaft 92?, having a suitable hand-wheel a". The shafts m and n are suitably mounted in the bracket O, which bracket is fastened to the hub of the gear e It will be observed that by turning the handle a this cam can be moved to shorten or lengthen the face of the cam e and allow the ductor-roll to dwell a greater or less length of time in contact with the fountain-roll E, and thereby take up more or less ink with which to supply the distributing-cylinder F. By

this means the operator is enabled to regulate the quantity of the ink to any desired degree, and that while the machine is in operation.

On the upper ends of the frames D and adjacent to the frame O is placed a stud P, which carries two links p and 19 which engage with the stud pion the frame C. The link 7 is slightly longer than the link 12 so that when it is desired to run the inking apparatus and distribute the ink Without putting the ink on the forms on the cylinder B the link 7) is attached to the stud p", which keeps the form-rolls f from coming in contact with the forms on the cylinder B and yet keeps the gear G in mesh with the main gear 7/ on the form-cylinder B. When the machine is ready to print, the link 19 will take the place of p and hold the inking apparatus in proper pos'ition. Instead of the links 17 and 79 any other fastening, such as a bolt of any suitable kind passing through one of the two frames D, as shown at Q, may be used, it being understood that any other suitable means can be used to hold the inking apparatus in the two different positions referred to.

From the foregoing it will be seen that I have provided a suitable inking apparatus which in its several movements is entirely self contained in the frames D and which can be run back from its working position inorder to facilitate the adjusting of the platesfonthe cylinder B and the rollers in the inking apparatus and which can be in turn either driven by hand by means of a handle or lever connected to any suitable part of the inking apparatus or which can be run with the gear ing in contact, so as to run the inking apparatus without placing the ink on the forms until such time as the machine is ready to begin printing on the sheets or Web of paper.

Of course it is not necessary to run the ink ing apparatus from a gear on the plate-cylinder. It might be operated by means of a train of gears from another part of the machine, and the gears might be run in contact without putting the ink on the forms.

I show a modification of the adjustable cam in Figs. 7 and 8. Instead of using the worm and worm-gear in order to turn the pinion m I simply put the hand-wheel n on the end of the shaft m and I provide atoothed wheel R into the detents of which are pressed a spring '1' to keep the cam e from changing its position while in operation. This detent-Wheel and spring may be constructed in any other manner suitable for the purpose, or it may simply have a friction applied, so that it will not allow the cam e to change its position.

In Figs. 11 and 12 I show a second modification by placing on the outer end of the shaft m the gear-wheel S and meshing with it and preferably in line with the shaft (2 and constructed to slide around in same the pin-gear 3, consisting of two teetlnand extending there- IIO from a suitable hand-wheel .9 The construction and operation of the pin and gear wheels are well known, and by using this it will be understood that adjustment can be had only a certain distance, after which the parts jam so that displacement is impossible.

In case the double cam, with its adjusting means, is placed on the other end of the fountain-roll shaft a more simple mechanism may be used to adjust the sameas, for instance, shown in Figs. 9 and 10in which case a spurgear tand a pinion t are utilized, the handle being mounted on the shaft "m or the device shown in Figs. 13 and 14, where a worm-gear t and worm t are used. Other modifications too-numerous to mention might of course also be used to accomplish the same purpose.

It is of course obvious that the cams a and may be mounted on a shaft separate from the fountain-roll, in which case the ductor-roll would make one vibration or two or more vibrations, as the case might be,with each revolution of the cams, the speed of the fountainrol-l being immaterial.
